According to our invention we provide in a loom provided with threeshuttle-boxes or in a loom provided with four shuttle-boxes anarrangement of a crank-pin and a crank, which may be turned into andheld in the various positions requisite by the turning into and holdingin certain positions of one or other or both of two disks to which wecause motion to be imparted by means of racks, and one of which disks weprovide with a stud or crankpin upon which is mounted the said crank,which can be turned about such crank-pin or stud by means of the seconddisk.

In order to facilitate the description of the arrangements which weemploy, we will first describe the arrangement of crank-pin or stud andcrank which we employ and the disks used with such arrangement ofcrank-pin or stud and crank, and the means by which such disks areturned into and held in the required positions, but as each disk whichwe employ in a loom, whether suchloom be provided with three or fourrising-and-falling shuttle-boxes, is moved into and held in thepositions requisite by means of parts which are in part the same as, andin part similar, to the parts by which the other disk used in such loomismoved'into and held in-the positions requisite, we-will in theaccompanying drawings, except in the case of the disks employed and thecrank-pin or stud and crank carried thereby,

apply the same letters of reference to each of lar parts thereference-letter applied to the disk in conjunction with which such partis employed. 2

In Figs. 1, 2, 3, 4c, and 5, a b are the two disks employed in ourarrangement for effecting the movement of the rising-and-fallingshuttle-boxes. The disks a b are respectively mounted fast upon axles ca0b, which are respectively mounted and capable of being revolved inbrackets dc db, each of which is secured to one arm of a bracket 6,secured to one of the end frames of the loom, that is to say, to the endframe 6. Upon the disk a is formed a pinion fa and upon the disk I) isformed a pinion fl). Fast with the disk a is a stud or crank-pin g,carried by and free to be turned, upon which is an arm or crank it. Fastwith the arm orcrank his a stud orcrankpin j, which is embraced by theupper end of a connecting-rod 7c, the lower end of which is jointed to alever m, carried by and free to be oscillated on a stud 71, carried by abracket secured to the end frame e of the 100m. To the lever m isjointed the lower end of aconnecting-rod 0, secured at its upper end tothe rising-and-falling shuttle-boxes 1, 2, 3, 4:. The stud or crank-pinj projects into a radial slot bf, formed in the disk I), the said slotproviding a sliding engagement between the crank-pin and the disk Z). I

As the disks to b, crank-pins or studs g and j, and arm or crank h forman important part of our invention by whatever means the disks a b maybe turned, we will now describe the mode in which such disks a b,crank-pins or studs 'gj, and arm or crank 72, actuate therising-and-falling shuttle-boxes 1, 2, 3, and 4: without referring tothe means shown in the accompanying drawings as being employed to impartmotion to the said disks CL Z).

If while the disk at is allowed to remain stationary in the position inwhich it is indicated in Fig. 5, the disk I) be turned through onehalfof a revolution from the position in which it is indicated in Fig. 5,the crank or arm 71 will be turned about the crank-pin or stud g fromthe position in which it is indicated in Fig. 5, in which the crank-pinor stud j is above the crank-pin or stud g, to a position in which thecrank-pin or stud j is below the crank-pin or stud g, and a furtherturning of the disk Z) through half of a revolution into the position inwhich it is indicated in Fig. 5 will cause the stud or crank-pinj to beagain above the stud or crank-pin g. If while the disk Z) is allowed toremain stationary either in the position in which it is indicated inFig. 5 or in the position in which it is when turned through half arevolution from the position in which it is indicated in Fig. 5, thedisk a be turned through half of a revolution from the position in whichit is indicated in Fig. 5, the crank-pin or stud gwill be turned into aposition in which it is below the axis of the disk a and cause the studor crank-pin j to be moved downward in the slot 7) of the disk I), andbya further turning of the disk IIS a through half of a revolution intothe position in which it is indicated in Fig. 5 the crankpin or stud 9will be turned again into the position in which it is above the axis ofthe disk a, that is to say, into the position in which it is indicatedin Fig. 5, and the stud or crank-pinj will be moved upward in theslot 1) of the disk I). It the disks a b be both turned simultaneously,so that each of them is turned through half of a revolution from or intothe position in which it is indicated in Fig. 5, the stud or crank-pin jwill be moved from the position at a certain distance above or below theaxes of the disks a b, in which it was at the commencement of the saidturnin g of the disks a b, to a position at an equal distance below orabove the axes of the disks a Z1. The crank-pin or stud j being embracedby the upper end of the connecting-rod 7c, the upward and downwardmovements of the crank-pin or stud 3' will respectively cause downwardand upward movements of the shuttle-boxes 1, 2, 3, and 4, and theeccentricity of the stud or crank-pin g in relation to the disk a beingsuch that the turning of such stud or crank-pin from its highestposition to its lowest position, and the turning of such stud orcrank-pin g from its lowest posi tion to its highest position willrespectively cause the shuttle-boxes 1, 2, 3, and 4 to be raised andlowered through a distance equal to the distance between the center ofone shuttle-box and the center of the next shuttlebox, and theeccentricity of the crank-pin or stud j in relation to the crank-pin orstud g being such that the turning of such crank-pin orstud j from aposition above the crank-pin.

or stud g to a position below the crank-pin or stud g, and the turningof such crank-pin or stud 3' from a position below the crank-pin or studg to a position above the crank-pin or stud g will respectively causethe shuttleboxes 1, 2, 3, and at to be raised and lowered through adistance equal to twice the distance between the center of oneshuttle-box and that next to it, the turning of one or other or both ofthe disks a b necessary to place such disks a b in any one of theseveral positions relative to each other in which they are indicated inFigs. 13 and 1%, Figs. 15 and 16, Figs. 17 and 18, and Figs. 19 and 20of the accompanying drawings will enable any one of the fourshuttleboxes 1 2 3 i to be brought into position to deliver or receive ashuttle.

\Ve will now describe the arrangements by means of which we enable thedisks which we employ to be held securely in the positions into whichthey may be turned from time to time and the arrangements by means ofwhich we enable the turnin or remaining stationary of such disks to becontrolled by means of the pattern-card chain which we employ,whetherthe said pattern-card chain be employed in conjunction with mechanism bymeans of which such pattern-card chain may while the loom is weaving becaused to revolve forward or backward or remain stationary for anydesired number of revolutions of the tappet-shaft of the loom, as in thearrangements illustrated in Figs. 1, 2, 3, and 4, or whether suchpattern-card chain be employed in conjunction with mechanism by which itis caused to revolve in one direction only while the loom is weaving,and only revolve in the opposite direction when the loom is turnedbackward for unweavin g or any other purpose, as in the arrangementsillustrated in Figs. 21, 25, 26, and 27.

q is a crank-pin secured in an arm q, mounted fast upon the shaft 1',which may be the tappet-shaft of the loom, as in the arrangementsillustrated in the accompanying drawings, or may be any other shaftwhich revolves at a suitable speed while the loom is weaving. Thecrank-pin q is embraced by the lower end of a connecting-rod 3,connected by means of a stud s to one end of an arm 251), which isformed upon a boss 25 mounted fast upon an axle 2?, upon which boss 15there is also formed an arm ta. The axle t is carried by and capable ofbeing oscillated in the bracket 6-. To the arm ta, by means of a stud,is connected a toothed rack ua, capable of being at times caused toengage with the pinion fa, and to the arm to a toothed rack ub, capableof being at times caused to engage with the pinion fb, is connected bymeans of a stud. The revolution of the crank-pin q will cause the arms atb to be oscillated about the axis of the axle t and will cause theracks ua ab to be raised and lowered. Carried by the bracket 6- is ashaft Q1, upon which and capable of being oscillated thereon are mountedbell-crank levers 'wa wb. The bell-crank lever wa is formed with a catchadapted to engage with either of two notches formed in the disk a, andthe bell-crank lever wb is formed with a catch adapted to engage witheither of two notches formed in the disk I). Springs 00a xb, secured tothe bracket 6 and bearing, respectively, against the bell-crank leverswa wb, tend to press such bell-crank levers 'wa wb into engagement withthe disks (1 b, respectively. Then the bell-crank lever wa or wb,employed in conjunction with either of the disks a b, is in engagementwith either of the notches in such disk the said disk will be preventedfrom rotating. In the bracket 6 are mounted needles or darts ya yb,which are capable of being moved lengthwise in the said bracket 6. Theneedle or dart ya is formed with a shoulder which abuts against thelower arm of the bell-crank lever wa, and such needle or dart ya abutsat one end against the back of the toothed rack ad. The needle or dartyb is formed with a shoulder which abuts against the lower arm of thebell-crank lever wb, and such needle or dart yb'abuts at one 'endagainst the back of the toothed rack ab.

The racks ua ub, being situate to one side of the studs on which theyare respectively mounted, tend to turn away from and out of gear withthe pinions fa fb, in conjunction with which they are respectivelyemployed.

Carried by the bracket 6 is a shaft or stud a, mounted and capable ofbeing oscillated, upon which is a frame 9. In the frame 9 and capable ofbeing revolved therein is mounted a pattern-chain barrel 10, aroundwhich passes a pattern-card chain 11, the construction of which isillustrated by Fig. 7 which shows a portion of such pattern-card chain.

The means by which the pattern-chain barrel 10 is revolved will behereinafter described.

13 is a cam which is secured in position upon the tappet-shaft r of theloom in the arrangements illustrated in the accompanying drawings, butmay be mounted upon any other shaft revolving at a suitable speed. Thecam 13 is secured in position upon the tappetshaft r by means of aset-screw passing through a slot formed in such cam 13 and screwed intoan arm mounted fast upon the tappet-shaft r, the said slot and set-screwenabling the cam 13 to be adjusted into and secured in position upon thetappet-shaft r. The cam 13 by acting against a bowl 14, mounted upon anarm 15, formed upon the frame 9, causes such frame 9 to be oscillated inthe direction indicated by the arrow A, and a spring 16, secured at oneend to the arm 15 and at the other end to the end frame 6 of the loom,causes such frame 9 to be oscillated in the direction opposite to thatindicated by the arrow A. hen the frame 9 is caused to move in thedirection indicated by the arrow A, the pattern-card chain 11 around thebarrel 10 will be moved toward the darts or needles ya yb, and by cardsor plates adapted to act upon one or other or both of such darts orneedles ya 'yb being provided at any part in the pattern-card chain 11,one or other or both of such darts or needles ya 3 may be caused to bemoved longitudinally in the direction indicated by the arrow B in eachrevolution of the tappetshaft 0', while if a card or plate or a suitablenumber of cards or plates adapted to leave either or both of the dartsor needles ya yb unacted upon either or both of such darts or needles ya3 may be caused to remain unacted upon by the pattern-card chain 11during a revolution or any required number of revolutions of thetappet-shaft r. WVhen either of the darts or needles ya 3 is movedlongitudinally in the direction indicated by the arrow B, the toothedrack ua or tab, in conjunction with which such dart or needle isemployed, will be caused to gear with the pinion fa or fl) upon the diska or b,in conjunction with which such rack no or ub is employed, and thebell-crank lever wa or wb used with such disk will be moved out ofengagement therewith.

The cam 13 and crank-pinqare so arranged that when the loom is weavingthe dart or needle or darts or needles moved by the pattern-card chain11 by any movement of the frame 9 in the direction indicated by thearrow A will cause the engagement of the rack or racks with which suchdart or needle fa or fl) in conjunction with which it is used' it willbe kept in gear therewith, while the continued revolution of thecrank-pin q causing the descent of such racks causes the said pinion andthe disk a or b on which such pinion is formed to revolve through half arevolution in the direction indicated by the arrow 0, and when the rackshave been moved to their lowest position the frame 9 will be allowed tomove in the direction opposite to that indicated by the arrow A, andcause the pattern-card chain 11 to recede from the dart or needle ya oryb or darts or needles ya and yb and allow the dart or needle or dartsor needles previously forced in the direction indicated by the arrow Bto be moved in a direction. opposite to that indicated by the arrow B bythe bell-crank lever or bell-crank levers, which bears or bear againstsuch dart or needle or darts or needles beingmoved by the spring orsprings 00 used therewith into engagement with the disk a or b or disksto b in conjunction with which such bell-crank lever or bell-cranklevers is or are used. When the dart or needle which has acted on eitherof the racks is withdrawn therefrom, the rack upon which it acted willfall away from and out of gear with the pinion on which it acted. WVhenthe bell-crank lever wa or wb, used in conjunction with either of thedisks a b, is in engagement therewith, such disk will be prevented frombeing turned, so that the bell-crank levers serve to retain theshuttle-boxes 1 2 3 4 in any position in which they are placed or causedto remain by the action of the pattern-card chain 11.

We will now describe the arrangements by means of which we enable thepattern-card chain employed in a loom to be caused to revolve forward orbackward or remain stationary for any desired time while the loom isweaving, which are illustrated in Figs. 1, 2, 3, and 4 of theaccompanying drawings. In these arrangements for enabling thepatterncard chain used for causing or controlling the raising andlowering of the shuttle-boxes employed in a loom to be caused to revolveforward or backward, or remain stationary for any desired time while theloom is weaving, which are particularly applicable for use in weavingpatterns in which one portion of the pattern occurs at intervals andanother portion is repeated several or a considerable number of times insuccession, a lag-chain 17, passing around a lag-barrel 18, mounted andcapable of being revolved upon a stud 19, carried by the bracket 6, isemployed. The lagchain 17 is formed of lags of three different heights,such as the lags 17 17 17 Fast with the lag-barrel 18 is a toothed wheel20. Upon a stud secured to the arm id is mounted a rack 21, which may becaused to engage or gear with the toothed wheel 20. In the bracket e ismounted a dart or needle 22, provided with an arm 22*, by means of whichthe rack 21 may be moved into gear with the toothed wheel 20. The arm 22upon the dart or needle 22 passes into a slot formed in the rack 21. Aspring 23, secured to the bracket 8, and shown in Fig. 6 as being formedin one with the springs are wb, tends to move the dart or needle 22 inthe direction opposite to that indicated by the arrow B. Secured to thebracket 6 is a stud 24;, mounted upon which and free to be oscillatedthereon is a bellcrank lever 25. The bell-crank lever 25 is providedwith a bar or finger 25 which projects over and is supported by the lagsof the lag-chain 17. The bell-crank lever 25 is provided with jaws 25which pass into a groove formed in a collar fast upon an axle 26,supported by and capable of being slid longitudinally and oscillated inthe bracket- 6. Fast upon the axle 26 is an arm 27, provided withprojecting pegs or studs 28 29. In the arm 27 is formed a slot, intowhich passes a pin 30, fast with an arm 31, secured upon the axle 25.Fast upon the axle of the patternchain barrel is a notched wheel 32, andalso fast upon the said axle is a toothed wheel 33, which gears into atoothed wheel 34, carried by and free to be turned upon a stud 35,secured to a bracket 36, secured to the frame 9. Fast with the toothedwheel 34 is a notched wheel 37 The notched wheels 32 and 37 the pegs orstuds 28 and 29, and the toothed wheels and 3% are shown more clearly inFig. 8.

\Vhen the axle is oscillated by the revolution of the crank-pin q, thearm 31 and pin will cause the arm 27 to be oscillated about the axis ofthe axle 26. When the axle t is oscillated in the direction indicated bythe arrow D, the pin 30 will cause the arm 27 to be oscillated in thedirection indicated by the arrow E, and when the axle t is oscillated ina direction opposite to that indicated by the arrow D the pin 30 willcause the arm 27 to be oscillated in the direction opposite to thatindicated by the arrow E. As is clearly indicated in Figs. 2 and 8, thepegs or studs 28 and 29 are formed in such positions upon the arm 27that according to the position in which such arm 27 and the axle 26 uponwhich it is mounted may be placed the peg or stud 28 may be placed inthe plane of the notched wheel 32, or the peg or stud 29 may be placedin the plane of the notched wheel 37 or both of such studs 28 29 may beso placed as to be incapable of passing into engagement with either ofthe notched wheels 32 37. The placing of the arm 27 and axle 26 indifferent positions is accomplished by means of the lagchain 17 andbell-crank lever 25, as will be hereinafter described. Vhile the loom isweaving tlie movement of the arm 27 in the direction indicated by thearrow E will take place during the time in which the patterncard chain11 is withdrawn from the darts or needles ya yb, and while the notchedwheels 32 3,7 are in a position in which the peg or stud 28, if in theplane of the notched wheel 32, may be engaged therewith, or the stud 29,if in the plane of the notched wheel 37, may be engaged therewith, andthe movement of the arm 27 in the direction opposite to that indicatedby the arrow E will take place during the time in which thepattern-chain barrel 11 is being moved into a position in which a cardthereon may, if it act upon the darts or needles ya yb, press and holdthe racks ua ub in gear with the pinions fa and fl), respectively. Whilethe loom is weaving the movement of the arm 27 in the direction oppositeto that indicated by the arrow E will not cause any motion to beimparted to the notched wheel 32 or the notched wheel 37, although thepeg or stud 28 may be in the plane of the notched wheel 32, or the pegor stud 29 maybe in the plane of the notchedplane 37. lVhile the loom isweaving, if the peg or stud 28 is in the plane of the notched wheel 32,the turning of the arm 27 in the direction indicated by the arrow E willcause the notched wheel 32 and pattern-chain barrel 10 to be revolvedthrough a quarter of a revolution in the direction indicated by thearrow F in each revolution of the shaft r, and if the peg or stud 29 isin the plane of the notched wheel 37 the turning of the arm 27 in thedirection indicated by the arrow E will cause the notched wheel 37 to berevolved through a quarter of a revolution in the direction indicated bythe arrow G in each revolution of the shaft r, and so by means of thetoothed wheels 34 and 33 cause the pattern-chain barrel 10 to berevolved through a quarter of a revolution in the direction opposite tothat indicated by the arrow F in each revolution of the shaft 1'.

In the position in which the parts are indicated in Figs. 1, 2, 3, 4,and 8 the lag-chain 17 is holding the bell-crank lever 25 in suchposition that the jaws 25 hold the axle 26 in such position that the pegor stud 28 is caused to move in the plane of the notched wheel 32, sothat while the loom is weaving and the shaft '1' is revolving in thedirection indicated by the arrow H the pattern-card chain 11 will becaused to pass around the pattern-chain barrel 10 in the directionindicated by the arrow F so long as the cards or plates of thepattern-card chain 11, which are presented to the darts or needles ya,yb, and 22 by the pattern-chain barrel 10, are formed with holes whichcan pass over the endof the dart or needle 22, so that such dart orneedle 22 is not acted upon by such cards or plates, but when thepattern-chain barrel 10 presents to the darts or needles gay?) 22 aplate or card which ICC IIO

is imperforate at the portion thereof which is presented to the dart orneedle 22 the next movement of the frame 9 in the direction indicated bythe arrow A will cause the dart or needle 22 to be moved in thedirection inclicated by the arrow B, and so cause the rack 21 to beplaced in gear with the toothed wheel 20, so that the next downwardmovement of the rack 21 will turn the lag-barrel 18 in the directionindicated by the arrow J and cause the next lag of the lag-chain 17 tobe brought into position beneath the bar or finger 25. A typical portionof the pattern-card chain 11 is shown detached in Fig. 7 of theaccompanying drawings. To retain the lag-barrel 18 in position after ithas been turned by the rack 21, we secure to the lag-barrel 18 a disk38, having around its edge as many flattened portions as there arenotches in the lag-barrel 18 to receive the lags of the lag-chain 17.Secured to the bracket 6 is a spring 39, which bears upon the flattenedportions of the disk 38 and so tends to hold thelag-barrel18 steady inany position into which it is turned by the rack 21. The spring 39 anddisk 38 are shown in Figs. 11 and 12 of the accompanying drawings.

Should the turning of the lag-barrel 18 by the rack 21 bring a lag, suchas 17 into position beneath the bar or finger 25, the bar or finger 25will, by its weight, be caused to descend and rest upon such lag 17 andsuch movement of the bar or finger 25 will cause the jaws 25 of thebell-crank lever 25 to move the axle 26 and arm 27 in the directionindicated by the arrow K, thereby removing the peg or stud 28 out of theplane in which the notched wheel 32 moves and bringing the peg or stud29 into the plane in which the notched wheel 37 moves. Vhen the peg orstud 29 has been so moved into the plane in which the notched wheel 37moves, the next movement of the arm 27 in the direction indicated by thearrow E, caused by the continued revolution of the shaft 0' in thedirection indicated by the arrow H, will cause the peg or stud 29 toturn the notched wheel 37 in the direction indicated by the arrow G andcause the pattern-chain barrel 18 to be revolved in a direction oppositeto that in which it is revolved when the stud 28 acts upon the notchedwheel 32 while the loom is weaving. WVhen the turning of the lag-barrel18 by the rack 21 brings a lag, such as 17, into position beneath thebar or finger 25, the bar or finger 25, being raised, will move the axle26 and arm 27 in a direction opposite to that indicated'by the arrow K,and thereby move the peg or stud 29 out of the plane in which thenotched wheel 37 moves and bring the peg or stud 28 into the plane inwhich the notched wheel 32 moves. hen the peg or stud 28 has been somoved into the plane in which the notched wheel 32 moves, the nextmovement of the arm 27 in the direction indicated by the arrow E, causedby the continued revolution of the shaft 7* in the direction indicatedby the arrow H, will cause the peg or stud 28 to turn the notched wheel32 and patof the notched wheels ternchain barrel 18 in the directionindicated by the arrow F.

When the turning of the lag-barrel 1 8 brings a lag, such as 17, beneaththe bar or finger 25, the bell-crank lever 25 will be turned and movethe axle 26 and arm 27 into such position that the pegs or studs 28 29will be clear 32 37 while the arm 27 is oscillating, and at such timesthe pattern-chain barrel 10 will not be rotated. hen the turning of thelag-barrel 18 brings a lag, such as 17 beneath the bar or finger 25,

the next movement of the pattern-card chain 11 toward the darts orneedles ya I Z; 22 will again present to the dart or needle 2 the cardor plate which, acting on such dart or needle 22, caused the said lag 17B to be brought beneath the bar or finger 25, and so cause another lagof the lag-chain 17 to be brought beneath the bar or finger 25 and suchother lag may either cause the pattern-chain barrel 10 to be turned inone direction or the other or may allow such pattern-chain barrel 10 toremain unturned.

We thus enable the pattern-card chain 11 to be turned forward orbackward or caused to remain stationary from time to time, as may bedesired, and we are thus enabled to employ in weaving a given pattern apatterncard chain of less length than would otherwise be required inweaving such pattern.

The connecting-rods 7t 0 are respectively formed in two parts andprovided with springs 40 42. The spring 40 tends to force apart the endsof the connecting-rod k, in which it is employed, so that if theshuttleboxes 1 2 3 4 should from any cause be prevented from rising whenthe disks a b or either of them are or is turned to cause the raising ofthe shuttle-boxes 1 2 3 at no breakage or injury to the parts of theloom may be caused. The spring 42, connected at one end to the frameworkin which the shuttle-boxes 1 2 3 4c are mounted and at the other end toa strap 43, which passes around a pulley or roller 44:, mounted upon'astud secured in the lower part of the connecting-rod 0 and is secured tothe upper part of the said'connecting-rod 0, tends to raise theshuttleboxes 1 2 3 4 and to draw the two ends of such connecting-rod 0together and counteracts the weight of the shuttle-boxes 1 2 3 1, so asto insure that the shuttle-boxes 1 2 3 at shall be moved in accordancewith the movements imparted to the lever m. If from any cause theshuttle-boxes 1 2 3 4 should be prevented from descending when the disksa l), or either of them, are or is moved to cause the descent of theshuttle-boxes 1 2 3 4c, the spring 42 will allow the connecting-rod o tobe extended and so prevent any injury or breakage of the parts of theloom from being caused. The nut and lock-nut upon the connectingrod itserve to limit the extent to which such connecting-rod 7; may be allowedto be extended, and the nut and lock-nut upon the ICC connecting-rod 0serve to limit the extent to which such connecting rod may becompressed.

IVhen the loom illustrated in Figs. 1, 2, 3, and 4 is being turnedbackward for unweaving or any other purpose,the studs 28 29 will passclear of the notched wheels 32 37 when the arm 27 is moving in thedirection indicated by the arrow E and the pattern-chain 11, and it maybe one or other or both of the disks a b, as the case maybe, and it maybe the reversing-chain or lag-chain 17 and shuttle-boxes will bemaintained in proper position relatively to the pattern of the piece orcloth being woven. By means of the arrangements which we employ toeffect-or control the movements of the pattern-card chain 11 we areenabled to reverse the patterncard chain 11 on two picks or any multipleof two picks. I

In cases in which it is not desired to cause the pattern-card chain 11to be turned backward except when the loom is turned backward forunweaving or any other purpose we employ the arrangements illustrated inFigs. 21, 23, 24., 25, 26, and 27, which show a loom which,whilegenerally similar to the loom illustrated in Figs. 1, 2, 3, and 4, isprovided with a pattern-chain barrel 10, having mounted upon it anoggin-wheel 32, receiving motion by means of a stud 45, secured in anarm 46, secured upon the axle t, and is not provided with thearrangements above described as being employed to effect the reversingof the pattern-card chain 11 employed in the loom illustrated in Figs.1, 2, 3, and 4.

The pattern-chain barrels 10 employed in looms constructed according toour invention may be held steadyin the positions which they are requiredto occupy and prevented from being moved except when required by meansof any suitable appliancessuch, for instance, as that illustrated inFigs. 9 and 10.

If at any time itshould be necessary for either of the disks a b to bemoved by hand in order that the shuttle-boxes may be put in properposition relative to the pattern of the piece or cloth being, woven thecatch or hellcrank lever employed in' conjunction with such disk may bemoved by hand and caused to release such disk and allow it to be turnedin the manner requisite.

In the accompanying drawings the shuttleboxes and the means foroperating them are in Figs. 1, 2, 3, and l and Figs. 21, 25, 26, and 27shown as being upon the left hand of the looms, but it will be obviousthat looms may be constructed with the risingand-falling shuttle-boxesand the means for operating them at either side or at both sides, as maybe desired in any case.

The method of operating three rising-andfalling shuttle-boxes by meansof our invention will be understood from the preceding explanation ofthe method of operatin g four rising-and-falling shuttle-boxes.

The arran gements of disks, arms, an d crankpins employed according toour invention for effecting the movement of the shuttle-boxes of loomsare of a very simple character and enable us to insure that theshuttle-boxes shall be moved into the various positions requisite withprecision and without shock at the commencement and end of theirmovement, and also enable any shuttle-box to be brought into position todeliver or receive a shuttle, whatever shuttle-box may previously havebeen in position to deliver or receive a shuttle.

It is obvious that the disks a and b employed in accordance with ourinvention may be turned by means of racks operated otherwise than in themanner in which'the racks ua ub above described are operated.
